Genes affected

NOC2L (HGNC:24517): (NOC2 like nucleolar associated transcriptional repressor) Histone modification by histone acetyltransferases (HAT) and histone deacetylases (HDAC) can control major aspects of transcriptional regulation. NOC2L represents a novel HDAC-independent inhibitor of histone acetyltransferase (INHAT) (Hublitz et al., 2005 [PubMed 16322561]).[supplied by OMIM, Mar 2008]

The c.1852T>A (p.Y618N) alteration is located in exon 16 (coding exon 16) of the NOC2L gene. This alteration results from a T to A substitution at nucleotide position 1852, causing the tyrosine (Y) at amino acid position 618 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
